Twenty-four patients with far advanced malignant tumors, resistent to established chemotherapy,, were treated with the combination of MNU and Cyclophosphamide. The drugs were administered in six-day cycles sequentially. MNU in doses of 4 mg/kg body weight and Cyclophosphamide in doses of 8 mg/kg body weight were given. Results of treatment showed response (greater than 50% tumor regression) in 10 (42%) of the 24 treated patients. Seven remissions were complete and three partial. Patients with Hodgkin's disease, malignant melanoma and breast cancer responded to this combination chemotherapy. Objective remissions were obtained also in five of thirteen patients with primary or metastatic brain tumors and in five of nine patients with pulmonary metastases. Nausea and vomiting were the main toxic effects, especially after injections of MNU. Myelosuppression was noted in about 50% of treated patients. Since this combination of cytostatics showed significant antitumor activity, further investigations are necessary on a larger number of patients and in other types of malignant tumors.

Vincristine-high-dose methotrexate-citrovorum factor (VCR-MTX-CF) was administered preoperatively at weekly intervals to eight patients, four with primary tumors and four with pulmonary metastases. These patients had not received prior VCR-MTX-CF treatment. A similar treatment program was administered to five patients with pulmonary metastases who had received prior VCR-MTX-CF. Among the eight patients who had not received prior VCR-MTX-CF, complete responses were obtained in three with primary tumors (this was followed by surgical excision) and two with pulmonary metastases. Partial responses occurred in two additional patients. Partial responses were also obtained in two patients who had received VCR-MTX-CF. Chemotherapy and surgery in one patient with an extremity lesion resulted in preservation of the limb and useful function. The major toxicity was anorexia and weight loss. Other side effects included stomatitis, myelosuppression, hepatitis and transient renal impairment. The weekly program was highly effective when compared to responses obtained with the tri-weekly schedule utilized in previous studies.

One hundred twenty patients with metastatic malignant melanoma were randomized to receive either cyclophosphamide, 600 mg/m2 IV, on day 1 plus DTIC 200 mg/m2 IV days 1 through 5, or the same chemotherapy plus C. parvum 5 mg/m2 IV on day 8 and day 15. Therapy was repeated every 21 days. Although responses were observed in 13.8% of patients on cyclophosphamide plus DTIC versus 25.5% of patients on cyclophosphamide plus DTIC plus C. parvum, the median duration of remission was 15.6 weeks on chemotherapy and 13.0 weeks on chemotherapy plus C. parvum. Furthermore, survival was similar on both regimens (6.1 months versus 5.7 months, respectively). Favorable prognostic factors included metastatic disease confined to skin or lymph nodes (33% responses), performance status greater than 70% (24% response rate), and administration of three or more courses of chemotherapy (31% response rate). The dose limiting toxicity was myelosuppression, which was equal on both regimens. Chills and fever were common in response to C. parvum, and, rarely hypotension, cyanosis, or immune nephritis was observed. The addition of C. parvum to chemotherapy with cyclophosphamide plus DTIC is not recommended.

Forty-one evaluable patients with malignant melanoma resistant to other chemotherapeutic agents received 9 mg/m2 of piperazinedione every 3 weeks. Two patients had partial responses and one additional patient had stable disease. One of the partial responses occurred in a patient with subcutaneous metastases and the other occurred in a patient with pulmonary and osseous metastases. Both antitumor responses occurred in the 17 patients with a performance status of greater than or equal to 80%. The dose-limiting toxicity was myelosuppression; thrombocytopenia was more frequently observed than granulocytopenia.

MCCNU and cyclophosphamide are synergistic in animal tumor systems and have different chronology patterns for dose-limiting myelosuppression. The combination was employed in 49 patients with metastatic cancer with each drug administered on successive days and repeated at 6-week intervals. A total of 108 courses of therapy were monitored, and leukopenia (WBC less than 3,000 cells/mm3) and thrombocytopenia (platelets less than 150,000/mm3) were observed in 47 and 30%, respectively, at nadir days 15 and 22. No clinically beneficial effects were observed in 40 patients with measurable disease. Combination chemotherapy employing nitrosoureas have not, as in this study, generally demonstrated synergistic therapeutic effects possibly related to the low level of antitumor activity of nitrosoureas in solid tumors and the use of suboptimal doses for one of more agents in the combination.

Twenty-six patients with far-advanced epidermoid carcinoma of the head and neck were treated with cis-dichlorodiammineplatinum(II) (DDP) in high doses, utilizing the technique of concurrent mannitol-induced diuresis. All 26 patients had received prior radical radiotherapy to local disease, 14 had had major ablative surgical procedures, and all but five had been previously treated with chemotherapy. Responses were as follows (duration in months): two complete (2+, 6+), six partial (1, 2, 3, 4, 5+, 8+), ten minor (all but one less than 1.5), and eight no change or progression. Responses were seen in primary tumors, neck nodes, and pulmonary metastases. Nausea and vomiting were seen consistently in all patients but were never dose-limiting. Myelosuppression was mild, with only three patients developing platelet counts less than 50,000/mm3 and no patient with a wbc count less than 2000/mm3. Transient elevations of serum creatinine were common but no patient developed peak levels greater than 2 mg/dl. Transient tinnitus was also common although only four patients developed clinically significant hearing loss during the trial and DDP could be definitely implicated in only one instance. DDP in this dose and schedule is thus effective and safe therapy in a very heavily pretreated group of patients with advanced head and neck cancer and is now being used in combination with other agents in the initial treatment of these patients.

Thirty-two evaluable patients with metastatic carcinoma of the breast received chemotherapy consisting of BCNU plus cyclophosphamide followed in 18 hours by Adriamycin. Treatments were repeated every 4 weeks. Complete or partial responses were observed in 14 patients (43.7%) and in 12 of 27 drug-resistant patients (44.4%). An additional 26% of patients had objective improvement, for an overall objective response rate of 70.4% in drug-resistant patients. Skin, lymph node, and soft tissue metastases more frequently responded to therapy, while hepatic, peritoneal, and osseous metastases responded with an intermediate frequency. Pulmonary, pleural, and central nervous system metastases did not respond to therapy. The median duration of complete and partial responses was 6.8 months, and the median survival of these patients was 9.6 months. Overall, the median survival of all patients in this study was 6.5 months. The dose-limiting toxicity was myelosuppression, particularly granulocytopenia. Congestive heart failure and stomatitis were rare. This combination of drugs is a reasonably well-tolerated regimen for treating advanced breast carcinoma in an ambulatory setting, and produces a high rate of objective antitumor response of moderate duration.

The inoperable bronchial carcinoma tends to early formation of metastases. If the tumor responds well to different cytostatic drugs, chemotherapy is absolutely necessary. In this case, combined therapy has better results than monotherapy. We use chemotherapy prior to radiotherapy in order to prevent hematogenic extension of the disease and to ameliorate the receptiveness of the primary tumor. In order to avoid local recurrence it is necessary to submit the primary tumor and the mediastinum to radiotherapy. A focal dose of 3000 rd within three weeks is considered to be sufficient. This dose generally does not cause severe myelosuppression, so that the chemotherapy can be continued. A report is given on the provisional results of different chemotherapeutic combinations. Further studies, however, are absolutely necessary in order to be in a position to give recommendations of common validity.

Twenty-one patients with advanced metastatic cancer received amphotericin B (AmB) plus BNUC in a Phase I chemotherapy trial. Of 11 patients with measurable metastases from bronchogenic carcinoma, five had partial antitumor responses lasting 1.5 to 12+ months, and one had objective improvement. Only two of six patients with other types of tumors had objective improvement of short duration. No consistent evidence of immunologic stimulation was observed in eight patients studied. These results suggest that amphotericin B may increase the therapeutic ratio of BCNU, and further trials of this new concept in chemotherapy of advanced tumors are in progress. The dose-limiting toxicity was myelosuppression, usually thrombocytopenia. No enhancement of BCNU toxicity by the addition of AmB was observed. The recommended dose for future studies is: AmB, 7.5 mg/m2 on day 1, 15 mg/m2 on day 1, 30 mg/m2 on days 3 and 4; plus BCNU, 250 mg/m3 on day 4. The regimen is repeated every 6 to 8 weeks.

Eighty-two patients with metastatic tumor received a therapeutic regimen consisting of BCNU, 100 mg/m2, and cyclophosphamide, 400 mg/m2, both intravenously on day 1, followed by adriamycin, 40 mg/m2, on day 2. Treatment was repeated every 4 weeks. Of 14 evaluable patients with adenocarcinoma of the breast, all resistant to previous chemotherapy and 12 resistant to a five-drug combination chemotherapy program, 12 had objective responses of which seven were good partial responses. Osseous, visceral, and cutaneous metastases responded equally well. Overall, 53% of 68 evaluable patients had objective responses, and 32% had complete or good partial responses. The most encouraging results were in patients with carcinoma of the head and neck, ovarian carcinoma, and multiple myeloma refractory to standard therapy. Significant responses were observed in previously untreated patients with epidermoid carcinoma of the lung, carcinoma of the prostate, and carcinoma of undermined primary. Remissions lasted a median of 5 months. Myelosuppression was moderate in degree and was maximal 2 weeks after treatment. Cumulative thrombocytopenia was apparent but not dose limiting with repeated courses.
